To all whom t may concern:

Be it known that I, JOHN a subject of the King of Great Britain andIreland, residing at Huddersfield, in the county of York, England, haveinvented a new and useful Improvement in Machines like, of which thefollowing is a specification.

This invention relates to certain improvements in machines or apparatusfor the dyeing, washing, or other liquid treatment of wool, rags,shoddy, and the like.

In these processes an apparatus has ordinarily been employed consistingof a vat or receptacle divided into upper and lower compartments bymeans ofa .perforated plate, and having a central :circulating tubeleading from the lower compartment and extending upwardly through theupper compartment to -a poi'nt above the level of the liquid withinthe'vat, the circulation being set up and maintained (up the centraltube and down through the material and perforated plate) by means ofsteam or compressed air introduced into the lower comartment by way of asupply main and perorated coil. In this known type of apparatus it hasalso been proposed .to introduce the coloring matter into the vat by wayofa funnelv or like receptacle having a branch pipe connection to thesaid steam or compressed air supply main. It has also been proposed inanother type of apparatus to lift and Iagitate the material withintheupper compartment ofthe vat by means of compressed air introducedinto the lower compartment by way of a supply main and perforated coiland from thence passed upward through the perforated plate and throughthe material.

My present invention relates to the aforesaid type ofapparatus havingthe upper and lower compartments, the intermediate perforated plate, thecentral circulating tube, and the steam supply main, and my improvementconsists mainly in the combination therewith of an auxiliary supply pipedesigned to introduce an auxiliary supply of air into the lowercompartment and to pass same upward through the perforated plate for thepurpose of lifting and agitating the material, said auxiliary air supplybeing controlled by a steam-operated air injector having-a branchconnection from the steam supply main, and said auxiliary air-supplyHENRY MILNES,

being utilized either separately or concurrently with the ordinary'steamsupply so as to obtain either a single or a double circulation. Afurther feature of my invention lies in the introduction of the coloringmatter by way of a branch connection to the auxiliary air supply pipe.

he accompanying drawing shows an elevation in section of a dye vat ofthe type referred to and having my 'improvements applied. Y

D is partment E, lower compartment F, intermediate'perforated plate G,central circulatingI tube I, and steam supply main K with valve L.

' According to my invention the steam sup-- ply main K is provided witha branch pipe M having valve J, this branch steam pipe M beingoperatively connected to an air injector I-I fitted in an auxiliary airsupply pipe A, which is carried down through the vat into the lowercompartment Fand terminates in a perforated coil B around the bottom ofthe vat'. The auxiliary air supply pipe A is also fitted with a branchpipe N having a valve O and an ordinary inlet funnel C for the dyeliquid or coloring matto the perforated coil B, from whence it 1s forcedthrough the perforated plate G-and up through the material, agitatingand lifting the material throughout without the necessity for stangingor poling. The ordinarysteam supply through the main K for the heatingcirculation, and the auxiliaryv air supply through the branch A for thelifting the ordinary vat, having upper comcirculation, .may be utilizedeither separately or concurrentlyas desired. The dye liquid or colorinmatter is introduced by way of l the inlet nnel'C and branch pipe N,`and is forced down the pipe .A and delivered along with the auxiliaryair supply from the perforated coil B, thus insuring eective istributionand thorough mixing with the liquor within4 the vat. v l' I claim 1. Indyeing l the I; vhaving. the ordinary upper apparatus and the like` ol l,bination therewith k signed to introduce an auxiliary supply of lowercompartments, intermediate` perforated plate, central circulating tube,and steam supply main, the employment in comof an auxiliary. pipe deairinto the lower compartment and to pass same upward through theperforated platel for the purpose of lifting the material, saidauxiliary air supply being controlled by a steam operated air injectorhaving a branch 'connection from` the steam supply main, and saidauxiliary airsupply and ordinary steam a ,supplyv being utilizableeither separately or forth. l n 2. In dyeing apparatus and the like of`the type having the ordinary 'upper -andconcurrently, substantially asherein set lower compartments, intermediate perforated plate, Hcentralcirculating tube, and steammamies -suppl main, the employment incombina-- tion t e erewith of an auxiliary ipe designed to introduce anauxiliary. supp y of air into the lower compartment and to pass same up-Vward through the perforated plate for the purpose of lifting thematerial, said auxil; iaryair supply being controlled by a steamoperated air 1n]ector having a branch coni Witnesses:
